The potential to remove Pb (II) from aqueous solutions through adsorption using Ailanthus Excelsa tree bark was investigated. The effects of pH, contact time, initial concentration and adsorbent dosage on the adsorption of Pb (II) were studied. The different experimental conditions were investigated in this study. It was observed that the amount of Pb(II) adsorbed increases rapidly initially, then system approaches equilibrium within 360 minutes. The extent of Pb (II) removal increased with increase in time and adsorbent dosage. The reaction kinetics was studied using different models. Langmuir and Freundlich adsorption model is used for the mathematical description of the adsorption equilibrium and isotherm constants are evaluated. Equilibrium data fitted very well to the Langmuir and Freundlich model.
